Can Water Heaters Explode? Here’s What You Need to Know.

A water heater leaking from the base

If you’re a homeowner in Austin, San Antonio, or the surrounding areas of Central Texas, you might have wondered about the potential dangers of your water heater. Can water heaters actually explode? The answer is yes, but it’s rare. Radiant Plumbing & Air Conditioning, a trusted name in plumbing and HVAC services, is here to shed light on this topic and help you keep your home safe.

Why Water Heaters Explode

Water heaters can explode due to a buildup of pressure inside the tank. This usually happens when the temperature and pressure relief valve (T&P valve) fails or is blocked. The T&P valve is designed to release excess pressure, but if it malfunctions, the pressure can rise to dangerous levels.

Another cause of water heater explosions is sediment buildup at the bottom of the tank. Over time, minerals in the water can settle and form a layer of sediment that can overheat and cause the water to boil, leading to increased pressure.

Signs of a Potential Problem

To prevent a water heater explosion, watch out for these warning signs:

  1. Popping or knocking sounds coming from the tank
  2. Leaking from the T&P valve
  3. Rusty or discolored water
  4. A rotten egg smell (indicates a gas leak)

If you notice any of these signs, call Radiant immediately. Our expert plumbers serve the Greater Austin and Greater San Antonio areas, including cities like Buda, Cedar Park, Boerne, and New Braunfels.

Tankless Water Heaters: Are They Safer?

Tankless water heaters, also known as on-demand water heaters, heat water as it flows through the unit. Since they don’t store water in a tank, they are less likely to explode. However, they can still pose risks if not properly maintained.

Radiant offers tankless water heater installation and repair services to help you enjoy the benefits of these efficient systems while ensuring your safety.

Preventing Water Heater Explosions

Regular maintenance is key to preventing water heater explosions. Here are some tips:

  1. Flush your tank annually to remove sediment buildup
  2. Test your T&P valve regularly to ensure it’s working properly
  3. Adjust the temperature setting to 120°F to reduce pressure buildup
  4. Schedule professional maintenance with the Radiant Care Club
